Given numbers are 505, 565, 318, 980
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(505, 565) = 57065
GCD(505, 565) = ( 505 x 565 ) / 57065
= 505 / 565
= 505
Step2:
LCM(5, 318) = 1590
GCD(5, 318) = ( 5 x 318 ) / 1590
= 5 / 318
= 5
Step3:
LCM(1, 980) = 980
GCD(1, 980) = ( 1 x 980 ) / 980
= 1 / 980
= 1
So, Greatest Common Divisor of 505, 565, 318, 980 is 1
